The way to learn multidisciplinary design has been discussed. “Biomedical engineering” is exemplified for multidisciplinary field. “Biomedical Engineering” makes the multidisciplinary research area, which includes biology, medicine, engineering, and others. The cross-cultural student seminars on biomedical engineering have been exemplified as the case studies. In the group work, students are divided into the small cross cultural groups. Each group finds a problem, methods to solve the problem, and contribution to the society. Presentations are made referring information on the internet. They have learned how to communicate with students, who have variety of cultural backgrounds. The training awakes students to several points: thinking from a different point of view, and variation of communication tools. The process is effective to learn multidisciplinary design.
